Delaware Income Tax Overview

Delaware levies a graduated personal income tax, meaning the rate rises as taxable income moves through a series of brackets rather than applying one flat percentage. The lowest brackets are taxed lightly, and the schedule tops out at 6.6% on income above the highest threshold. This state tax is calculated separately from, and stacks on top of, the federal income tax you already owe to the IRS, so a Delaware resident effectively files two returns each spring.

Residents are taxed on all income regardless of where it's earned, while nonresidents who work in Delaware are taxed on the Delaware-source portion. The state offers a standard deduction, $3,250 for a single filer, that reduces taxable income before the brackets apply, or you can itemize if that produces a better result. Delaware administers the tax through its Division of Revenue, which sets forms, brackets, and credits each year. Because the top marginal rate of 6.6% only hits the slice of income above the highest bracket, your effective rate, the share of total income actually paid, usually lands well below that headline number.

Delaware Income Tax FAQ

What is Delaware's top income tax rate, and when does it apply?
Delaware's personal income tax is progressive and tops out at 6.6%, but that rate only applies to the portion of taxable income above the highest bracket threshold. Income in the lower brackets is taxed at lower rates, so most filers pay an effective rate noticeably below 6.6%. The Division of Revenue publishes the bracket schedule that determines exactly where each rate kicks in.
Do I owe Delaware income tax if I live in another state but work here?
Generally yes. Nonresidents are taxed by Delaware on income sourced to work performed in the state, and they file a Delaware nonresident return. Your home state may give you a credit for taxes paid to Delaware to avoid double taxation, so it's worth checking how the two states coordinate.
How does the Delaware standard deduction work against the brackets?
The standard deduction lowers your taxable income before Delaware's bracket rates are applied. For a single filer it's $3,250, and you subtract it from income unless itemizing gives a bigger reduction. Lowering taxable income can also keep more of your earnings out of the higher brackets that lead up to the 6.6% top rate.
Is Delaware income tax separate from federal income tax?
Yes. The 6.6% top state rate is entirely separate from federal income tax and sits on top of it. You calculate your federal liability with the IRS and your Delaware liability with the state Division of Revenue using its own brackets, deductions, and credits, so the two bills are computed independently.
